Checking the Installed Devices
The HDD-1 or FDD-1 represents the first drive in the
system configuration, respectively. Similarly, the HDD-2 or
FDD-2 represents the second drive, usually attached
through a Dock II.
Notes:
1. Neither the Dock II nor the adapters and SCSI
devices installed in the Dock II appear as icons on
the screen.
2. HDD-1 and HDD-2 icons are for the 2.5-inch
ThinkPad hard disk drive.
If the devices are installed, but the icon appears in a gray
shade rather than a dark shade on the basic diagnostic
screen, it means that the devices are defective. Turn off
the computer and make sure that the devices are correctly
connected. If the symptom still remains after the computer
is turned on, replace the devices or the main card of Dock
II.
Dock II (3546) 397

Power Supply
If the power-on indicator is not on and the power supply
fan is not turning, check the power cord for continuity and
correct installation.
If the power cord is not the problem, either the power
supply is defective, or another component is defective
causing the power supply to cut off. To verify that the
power supply is operating correctly, do the following:
1. Turn off the computer and disconnect the Dock II
power cord.
2. Remove all internal and external devices, and the
computer from the Dock II.
3. Remove the power supply connector CN26 from the
main card (refer to “Main Card” on page 453) and
CN56 from the riser card (refer to “Riser Card” on
page 455).
4. Remove the SCSI power supply connector from the
SCSI device.
5. Install jumpers between pins 1 and 2, and pins 3 and
4 of JP2 on the main card.
6. Connect the Dock II power cord.
7. Check the power supply voltages on the CN26,
CN56, and SCSI connectors by referring to the
respective voltage tables. Then, check that the fan is
turning. If the voltage is not correct or the fan is not
turning, replace the power supply.
8. Connect the Dock II power cord.
If any of the voltages are not correct, replace the power
supply. If replacing the power supply does not correct the
problem, then replace the main card.
